Dieses Magnetventil 6 ist Druckluftleitung 16 abgebaut wird. Jetzt kann das Radüber eine Druckluftleitung 7 mit einem Vorwahlschalter steuerventil 14 durch einen zwischen dem Maximal- und 8 verbunden, an dem die pewünschten Drücke z.

Von den Relaisventilen 3 und 4 führen gemäßen Einrichtung das Radsteuerventil bereits ge-Druckluftleitungen 11 zu den Radachsendes Fahrzeug- schlossen ist, bevor die Druckluftleitungen entlüftet es.

Zwar ist das Radsteuerventil nur fangen 11 der am Vorwahlschalter 8 eingestellte Druck beim maximalen Reifenluftdruck, d. h. bei Straße-ifahrt herrscht geschlossen und damit die Ringkammerdichtung druckin Fig. 1 ist lediglich die Zuführeinrichtung für ein 25 frei; die Erfahrung hat jedoch gezeigt, daß dies weit Rad 2S der Vorderachse gezeigt, das außerdem in die überkompensiert wird durch die Möglichkeit, den Zeit-Zeichenebene gelegt wurde.

This is contrary to previous practice when the invention was made can. According to the device, the wheel control valve already leads from the relay valves 3 and 4 to compressed air lines 11 to the wheel axles of the vehicle is closed before the compressed air lines are vented it. The solenoid valve 6 can also be electrically operated with the mentioned manometer or the by means of a push button 9 on the one hand and a venting control lights mentioned the rapid venting of the Button 10, on the other hand, switchable, with the solenoid 20 compressed air lines open and thus the perfect closing valve 6, i.e. when pushbutton 9 is pressed, the ßen of the wheel control valve are made from the control station Relay valves 3 and 4 controlled in such a way that the pressure lines are controlled. True, the wheel control valve is only catch 11 the pressure set on the preselector switch 8 at the maximum tire air pressure, d. H. when driving by road it is closed and thus the annular chamber seal is pressure in FIG. 1, only the feed device for a 25 is free; however, experience has shown that this goes far Wheel 2S of the front axle is shown, which is also overcompensated in the by the possibility of the time drawing plane was laid. This wheel 26 needs to be pulled to reduce the tire air pressure other parts of the facility are also in such a maximum to its minimum pressure value to less Way to lower all other wheels of the vehicle by 15% of the previously necessary time.

Druckluftleitung 13 sowohl zu einem Radsteuerventil 14 als auch zu einem Oberströmventil 15 führt. Zwischen dem Überströmventil 15 und dem Radsteuerventil 14 ist eine weitere Verbindung in Gestalt einer Druckiuftieitung 16 vorgesehen. Der gewünschte Druck wird schließlich vom Radsteuerventil 14 über die Druckluftleitung 17 dem Luftreifen des Rades 26 zugeführt.Compressed air line 13 leads both to a wheel control valve 14 and to an overflow valve 15. Between the overflow valve 15 and the wheel control valve 14 is a further connection in the form of a pressure air line 16 provided. The desired pressure is finally obtained from the wheel control valve 14 via the compressed air line 17 supplied to the pneumatic tire of the wheel 26.
Aus der Schnittdarstellung von Radsteuerventil 14 und Überströmventil 15 mit den zugeordneten Druckluftleitungen 13, 16 und 17 gemäß Fig.2 ergeben sich die wesentlichen Einzelheiten.From the sectional view of wheel control valve 14 and overflow valve 15 with the associated compressed air lines 13, 16 and 17 according to FIG. 2 result the essential details.
Die Druckluftleitung 13 steht sowohl mit der Vorkammer 18 des Radsteuerventiles 14 wie auch mit der Vorkammer 19 des Überströmventiles 15 in Verbindung. Im Radsteuerventii 14 ist ein geführter Ventilteller 20 mit einstellbarer Feder 21 angeordnet Die Feder 21 wird, das gewählte Beispiel beibehaltend, auf den Mindestdruck für die Luftreifen, nämlich etwa 0,7 bar, eingestellt Vom Radsteuerventil 14 führt, wie schon gesagt die Druckluftleitung 17 zum jeweiligen Luftreifen.The compressed air line 13 is both with the antechamber 18 of the wheel control valve 14 and with the Pre-chamber 19 of the overflow valve 15 in connection. In the wheel control valve 14 is a guided valve plate 20 with adjustable spring 21 arranged. The spring 21 is, keeping the example chosen, on the Minimum pressure for the pneumatic tires, namely about 0.7 bar, set. As already mentioned, the wheel control valve 14 leads the compressed air line 17 to the respective pneumatic tire.
Das Überströmventil 15 ist ebenfalls mit einem geführten Ventilteller 22 und einer auf diesen wirkenden einstellbaren Feder 23 ausgestattet die, im Rahmen des Beispiels bleibend, auf den Maximaldruck von 23 bar eingestellt ist Der Abgang aus dem Überströmventil 15 erfolgt durch die Druckiuftleitung 16, die zum Radsteuerventil 14 dergestalt geführt ist, daß bei geöffnetem Überströmventil 15 der Überdruck auf die Rückseite (im dargestellten Beispiel die Federseite) des Ventiltellers 20 im Radsteuerventil 14 wirkt. Damit wird, sobald der eingestellte maximale Reifendruck erreicht ist, das Radsteuerventil 14 sicher geschlossen, da sich der Schließkraft noch die Federkraft der Feder 21 hinzuaddiert. Nach dem dergestalt erreichten einwandfreien Schließen des Radsteuerventiles 14 werden die Druckluftleitung 13, die Ringkammerdichtung 12 und dieThe overflow valve 15 is also with a guided valve plate 22 and one acting on this adjustable spring 23 equipped which, remaining within the scope of the example, to the maximum pressure of 23 bar The outlet from the overflow valve 15 takes place through the compressed air line 16, which leads to the wheel control valve 14 is guided in such a way that when the overflow valve 15 is open, the overpressure on the rear side (in the example shown the spring side) of the valve disk 20 acts in the wheel control valve 14. So that as soon as the set maximum tire pressure is reached, the wheel control valve 14 is safely closed, since the Closing force still the spring force of the spring 21 is added.
